Clinical and Radiological Mid-to-Long-term Outcomes Following Ankle Arthrolysis

Abstract

Background: The aim of this study was to evaluate the clinical and radiographic success of arthrolysis surgery and the risk of progression of osteoarthrosis at the ankle joint. Materials and Methods: In a retrospective clinical and radiological study, with a minimum follow-up of 24 months, the pain level and quality of living were evaluated. Results: Following arthrolysis of the ankle joint, 16% of patients required ankle fusion within 2 years. Women had a higher quality-of-life in terms of Foot Function Index. Younger patients scored higher in both quality-of-life and function scores. Radiographic osteoarthrotic changes and the specific follow-up interval did not correlate with clinical outcome. Conclusion: Fewer than 20% of patients required ankle fusion. Female gender and young age had a positive impact. Preoperative radiography and the postsurgical interval are poorly predictive for the progression of osteoarthrosis.
